● 6 samples provided and easy to change
● Large resonant amplitude, convienent for viewing on oscilloscope
● High homogeneity of magnetic field, assuring more coda waves
● Open structure of the magnet, coils visible, free moving of sample head
● Special design of the oscillator & detector, high SNR & frequncy stability
● Increased measurement points by using sweeping magnetic field
● One sample contains both H & F nucleus, directly determine g factor of F nuclei
● High accuracy milli-teslameter included.
This LEAI-11 Experimental System of Continuous Wave Nuclear Magnetic Resonance (CW MNR) consists of high homogeneity magnet and main machine unit. It has features of convenient operations, high SNR, and notable teaching effect. It is an ideal experimental instrument for advanced physics laboratories.
Using this instrument, the following experiment contents can be performed:
1.Observe nuclear magnetic resonance phenomenon of H nuclei, determine parameters: gyromagnetic ratio, g factor and nuclear magnetic moment, of F nuclei using comparison method
2.Observe the influence of magnetic field homogeneity to signal coda wave using different samples
3.Accurate measurement of magnetic field, learn to calibrate Teslameter through nuclear magnetic resonance method.
